/usr/include/stdio.h(254): error: attribute "__malloc__" does not take arguments

This looks like https://forums.developer.nvidia.com/t/cuda-11-5-samples-throw-multiple-error-attribute-malloc-does-not-take-arguments/192750

I'm not interested in fixing that. Either we merge this as is, as it is not the cause of the failure, or I'll close the PR as it'll never get fixed.
